There is a signal receiving method in the related art, in which the maximum scanning angle range of the phased array antenna is obtained, and then the phased liquid crystal array antenna is sequentially scanned within a maximum scanning angle range according to a preset scanning angle. To receive the signal.

The above signal receiving method adopts a sequential scanning method, and the time taken to receive the signal is long, and the efficiency of receiving the signal is low.

The display device can be a smart phone, a tablet computer or a smart TV. As shown in Figure 1, the method includes:

Step 101: Obtain a maximum scan angle range of the phased array antenna.

Step 102: Based on the power of the signal received by the phased array antenna, use a binary search method to reduce the maximum scan angle range until the difference between the maximum value and the minimum value of the reduced scan angle range is less than a preset value, and the reduced scan is performed. The angular range is used to receive signals.

When the difference between the maximum value and the minimum value of the reduced scan angle range is less than a preset value, the display device may receive the signal based on the reduced scan angle range by the phased array antenna.

In some embodiments, the preset value may be a minimum angular scan interval of the phased array antenna.

In some embodiments, the method further comprises aligning the main lobe of the phased array antenna with a direction of one of a maximum and a minimum of the reduced scan angle range to receive the signal.

In summary, at least some embodiments of the present disclosure provide a signal receiving method capable of acquiring a maximum scanning angle range of a phased array antenna and reducing the power of the signal received by the phased array antenna by using a binary search method. The maximum scan angle range until the difference between the maximum value and the minimum value of the reduced scan angle range is less than the preset value. Since the maximum scanning angle range is reduced a plurality of times by the binary search method, the time taken for the electronic device such as the display device to receive the signal is shortened, and the efficiency of the received signal is improved.

At least some embodiments of the present disclosure provide a signal receiving method, such as a processing component for use in a display device, as shown in FIG. 2, the method including the following steps 201 through 203:

Step 201: Obtain a maximum scan angle range of the phased array antenna.

For example, the maximum scan angle of the phased array antenna can range from -60° to +60°, as exemplified by FIG. For example, the maximum scan angle range of the phased array antenna can be pre-stored into the phased array antenna included or associated memory, whereby the maximum scan angle range of the phased array antenna can be obtained by reading the memory. For another example, the maximum scanning angle range of the phased array antenna may be preset, or determined according to a signal transmitted from the phased array antenna when the processing component is connected to the phased array antenna, wherein the phase control is performed. The signal transmitted by the array antenna may include information such as the type and model of the phased array antenna or information directly including the range of the maximum scanning angle. However, it should be understood that the embodiments of the present disclosure are not limited thereto.

Step 202: Determine an angle corresponding to the maximum scan angle range as a to-be-processed angle.

Referring to FIG. 3, in this step, the angle θ corresponding to the range of the maximum scanning angle can be determined as the angle to be processed.

Step 203: Perform an angle range reduction process.

As shown in FIG. 4, an example of step 203 may include the following steps (sub-steps) 2031 through 2036:

Step 2031: Check whether the angle of the to-be-processed angle is less than a preset value. When the angle of the to-be-processed angle is less than the preset value, step 2032 is performed, and when the angle of the to-be-processed angle is not less than the preset value, step 2033 is performed.

For example, the preset value can be 0.1°. Referring to FIG. 3, the angle of the angle θ to be processed is 120°. Since 120°>0.1°, that is, the angle of the angle to be processed is not less than the preset value, step 2033 is performed.

Step 2032: Determine an angle range corresponding to the to-be-processed angle as a reduced scan angle range.

When the angle of the to-be-processed angle is less than the preset value, the angle range corresponding to the to-be-processed angle is determined as the reduced scanning angle range. At this point, the reduction process of the maximum scanning angle range ends, after which the display device can pass through the phased array antenna. The signal is received based on the determined reduced scan angle range.

Step 2033: Divide the to-be-processed angle into two symmetrical corners according to the angle bisector of the angle to be processed. Go to step 2034.

In some embodiments of the present disclosure, it is assumed that the position of the signal to be received is located at the position of 59.96° in FIG. 3, referring to FIG. 3, the angle of the angle to be processed θ is not less than a preset value, then according to the angle θ to be processed The angle bisector x1 divides the to-be-processed angle θ into two symmetrical angles, which are θ1 and θ2, respectively. Wherein, the angle range corresponding to θ1 is (-60°, 0°), and the angle range corresponding to θ2 is (0°, 60°).

Step 2034: Control the direction of the main lobe of the phased array antenna to point to the direction of the angle bisector of the two corners. Go to step 2035.

Referring to FIG. 3, in this step, the processing component can control the direction of the main lobes of the phased array antenna to the direction of the angle bisector of the two corners (ie, θ1 and θ2), and the direction of the angle bisector of θ1 is as shown in FIG. The direction indicated by k1 (i.e., the direction indicated by -30°), the direction of the angle bisector of θ2 is the direction indicated by k2 in Fig. 3 (i.e., the direction indicated by 30°).

Step 2035: Obtain the power of the signal received by the phased array antenna in the direction of the angle bisector of the two corners. Go to step 2036.

Referring to FIG. 3, the processing component obtains the power P1 of the signal received by the phased array antenna in the direction k1 of the angle bisector of θ1, and the power P2 of the signal received by the phased array antenna in the direction k2 of the angle bisector of θ2.

In step 2036, an angle corresponding to the corresponding received signal power is selected as the new to-be-processed angle among the two corners, and step 203 is performed again.

Referring to FIG. 3, the signal power P2 received by the phased array antenna in the direction k2 is greater than the signal power P1 received by the phased array antenna in the direction k1, and the processing component uses θ2 as the new to-be-processed angle.

Thereafter, step 203 is performed again. Referring to FIG. 5, the angle of θ2 is 60°, which is not less than 0.1°, then the processing component divides θ2 into two symmetrical angles according to the angle bisector x2 of θ2, respectively. It is θ21 and θ22. Wherein the angle range corresponding to θ21 is (0°, 30°), and the angle range corresponding to θ22 is (30°, 60°), and the processing component controls the main lobe direction of the phased array antenna to point to two angles respectively (ie, θ21 and θ22) The direction of the angle bisector, the direction of the angle bisector of θ21 is the direction indicated by k21 in FIG. 5 (ie, the direction indicated by 15°), and the direction of the angle bisector of θ22 is the direction indicated by k22 in FIG. (ie, the direction indicated by 45°), after which the processing component obtains the power P21 of the signal received by the phased array antenna in the direction k21 of the angle bisector of θ21, and the direction k22 of the phase bisector of the phased array antenna at θ22 The power of the received signal P22. The signal power P22 received by the phased array antenna in direction k22 is greater than the signal power P21 received by the phased array antenna in direction k21, then θ22 is taken as the new to-be-processed angle.

Step 203 is performed again. Referring to FIG. 6, the angle of θ22 is 30°, which is not less than 0.1°, then the processing component divides θ22 into two symmetrical angles according to the angle bisector x3 of θ22, and the two angles are respectively θ31. And θ32. The angle range corresponding to θ31 is (30°, 45°), and the angle range corresponding to θ32 is (45°, 60°). The processing component controls the main lobe direction of the phased array antenna to point to two angles respectively (ie, θ31 and θ32). The direction of the angle bisector, the direction of the angle bisector of θ31 is the direction indicated by k31 in Fig. 6 (i.e., the direction indicated by 37.5°), and the direction of the angle bisector of θ32 is the direction indicated by k32 in Fig. 6 (ie, the direction indicated by 52.5°), after which the processing component obtains the power P31 of the signal received by the phased array antenna in the direction k31 of the angle bisector of θ31, and the direction of the angular bisector of the phased array antenna at θ32. The power of the received signal P32. The signal power P32 received by the phased array antenna in the direction k32 is greater than the signal power P31 received by the phased array antenna in the direction k31, and θ32 is taken as the new to-be-processed angle.

Step 203 is performed again, the angle of θ32 is 15°, which is not less than 0.1°, then the processing component divides θ32 into two symmetrical angles according to the angle bisector x4 of θ32, and the two angles are θ41 and θ42, respectively. The angle range corresponding to θ41 is (45°, 52.5°), and the angle range corresponding to θ42 is (52.5°, 60°). The processing component controls the main lobe direction of the phased array antenna to point to two angles respectively (ie, θ41 and θ42). The direction of the angle bisector, after which the processing component obtains the power P41 of the signal received by the phased array antenna in the direction k41 of the angle bisector of θ41 (ie, the direction indicated by 48.75°), and the phased array antenna at θ42 The power of the signal received by the angle bisector in the direction k42 (ie, the direction indicated by 56.25°) is P42. The signal power P42 received by the phased array antenna in direction k42 is greater than the signal power P41 received by the phased array antenna in direction k41, then θ42 is taken as the new to-be-processed angle.

By analogy, when the 11th angle range reduction process is performed, the angle of the new to-be-processed angle θ12 is 0.12°, which is not less than 0.1°, then the processing component divides θ12 into symmetry according to the angle bisector x11 of θ12. Two angles, θ12 and θ13, respectively. The angle range corresponding to θ12 is (59.88°, 59.94°), and the angle range corresponding to θ13 is (59.94°, 60°). The processing component controls the main lobe direction of the phased array antenna to point to two angles respectively (ie θ12 and θ13). The direction of the angle bisector, after which the processing component obtains the power P12 of the signal received by the phased array antenna in the direction k12 of the angle bisector of θ12 (ie, the direction indicated by 59.91), and the phased array antenna at θ13 The power P13 of the received signal in the direction k13 of the angle bisector (ie, the direction indicated by 59.97°). The signal power P13 received by the phased array antenna in direction k13 is greater than the signal power P12 received by the phased array antenna in direction k12, then θ13 is taken as the new to-be-processed angle.

Step 203 is performed again, and the angle of θ13 is 0.06, which is less than 0.1, then the angular range corresponding to θ13 (59.94°, 60°) is determined as the narrowed scanning angle range, and thus the narrowing process of the maximum scanning angle range ends. Thereafter, the display device can receive the signal based on the determined reduced scan angle range by the phased array antenna.

It can be seen from the above that with the signal receiving method provided by the embodiment of the present disclosure, when the position of the signal to be received is located at the position of 59.96° in FIG. 3, the processing component can receive the signal by performing the angle range reduction process for a maximum of 11 times.
